MULTIPART MOLD FOR PNEUMATIC TIRES.

Specification of Letters Patent.

Patented Nov. 2e, 1907.

Application filed January 28. 1907. Serial No. 354.413.

To all whom 'it may concem:

Beit kno'wn that I, FRIEDRICH VEITH, a subject of the Emperor of Germany, resident ot Veithwerk, near Hchst, in the Grand Duchy ot' liesse, Germany, have invented certain new and useful improvements in Multpart Molds for Pneumatic Tires7 ot' which the following is a specification.

My invention relates to molds forthe covers of pneumatic tires and particularly to molds which are made hollow, so that steam may be introduced to heat them.

'lhc object ot my linvention is to provide for a convenient means of removing from the hollow core employed in molds of the above indicated character water produced by the condensation of steam, and to do this by means .of a pipe passing betweenfthe edges of the cover, so that such edges Will. not be affected by the drain pipe.

My invention will be fully described hereinatter, and the features of novelty pointed out in the appended claims.

Reference 1s to be had to the accompanying drawing, wh' h is a vertical section of a mold constructed according to my invention.

b and c are the upper and lower portions respectively of the mold, provided. with' chambers b and c .for the. circulation ofsteam. c is the core, having a cham-ber c. These parts may be constructed in any suitable manner, and the novel feature of my invention consists in the provision oi a groove or gutter -e at `the bottom ot the chamber c into which groove dips the downwardl bent end of a drain pipe d, leading outwar ly between the edges of the tire cover. The sha. e of this tire cover is indicated by the outline of the core and of the upper and lower mold ortions. Steam is admitted to the cham er c through a pipe located in the same manner as the pipe d to pass between the edges of the tire cover. Any water produced by the condensation of steam 1n the chamber e/ will collect in the groove e and will be expelled through the pipe d by the pressure ot' the live steam.

The downwardly bent inner end of the pipe d forms a hydraulic seal in the gutter e. With this arrangement I secure a permanently uniform heating of the core, and this is the object of my invention.

I claim:

1. A mold for pneiiniatic tire covers comprising a core having an internal chamber and a ,utteror depression at the lower part of said densation water, and a drain pipe leading from said depression.

2. A mold for pneumatic tire covers ecmprising a core having an internal chamber and a depression or gutter' at thelower p01'- tion ci said chamber for the reception of condensation water, and a drain pipe having its inner end dipping into such depression to form a hydraulic seal.

3. A mold for pneumatic tire covers, comprising upper and lower sections, a core lccated between them, said core being chamberedV and having a depression in which the condensation water may collect, and a drain pipe leading from said depression and extending between the upper and lower mold sections, so as not to ail'ect the edges ot the tire cover.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing' witnesses.
